IviFgen Attribute Defined Values
| Attribute | Value Name | Defined Value | Description |
|---|---|---|---|
| OPERATION_MODE | OPERATE_CONTINUOUS | 0 | The function generator produces output continuously. |
| OPERATE_BURST | 1 | The function generator produces a discreet number of waveforms when a trigger event occurs. | |
| OUTPUT_MODE | OUTPUT_FUNC | 0 | The driver uses the attributes and functions of the IviFgenStdFunc extension group to configure the function generator's output signal. |
| OUTPUT_ARB | 1 | The driver uses the attributes and functions of the IviFgenArbWfm Extension Group to configure the function generator's output signal. | |
| OUTPUT_SEQ | 2 | The driver uses the attributes and functions of the IviFgenArbWfm and IviFgenArbSeq Extension Groups together to configure the function generator's output signal. | |
| REF_CLOCK_SOURCE | REF_CLOCK_INTERNAL | 0 | The function generator produces the reference clock signal internally. |
| REF_CLOCK_EXTERNAL | 1 | The function generator receives the reference clock signal from an external source. | |
| RTSI_CLOCK | 101 | The function generator receives the reference clock signal from the RTSI clock source. | |
| FUNC_WAVEFORM | WFM_SINE | 1 | Configures the function generator to produce a sinusoid waveform. |
| WFM_SQUARE | 2 | Configures the function generator to produce a square waveform. | |
| WFM_TRIANGLE | 3 | Configures the function generator to produce a triangular waveform. | |
| WFM_RAMP_UP | 4 | Configures the function generator to produce a positive ramp waveform. | |
| WFM_RAMP_DOWN | 5 | Configures the function generator to produce a negative ramp waveform. | |
| WFM_DC | 6 | Configures the function generator to produce a constant voltage. | |
| TRIGGER_SOURCE | EXTERNAL | 1 | The function generator does not produce an output signal until it receives a trigger on its external trigger input terminal. |
| SOFTWARE_TRIG_FUNC | 2 |
The function generator does not produce an output signal until the IviFgen_SendSoftwareTrigger function is called. If you set the IVIFGEN_ATTR_TRIGGER_SOURCE attribute to this value, the instrument can only be triggered by calling the IviFgen_SendSoftwareTrigger function. |
